Which primers are recommended for 7mm SAUM loads?

Primer Selection for 7mm SAUM

When selecting primers for 7mm SAUM loads, it’s essential to consider the specific characteristics of the cartridge. The 7mm SAUM is a high-pressure cartridge, and the primer must be able to handle the increased pressure without compromising performance.

The Federal 210M primer is a popular choice for 7mm SAUM loads. It has a high flash point and provides consistent ignition, making it suitable for hunting in a variety of conditions. The CCI 250 primer is another option, offering a slightly lower flash point and a more moderate burn rate.

Load Development and Testing

When developing a new load for the 7mm SAUM, it’s crucial to start with a small batch and gradually increase the charge weight. This will help you avoid overloading the cartridge and ensure that your load is safe and reliable. Begin with a starting charge of 45-50 grains of ballistic powder and gradually increase the charge in 2-3 grain increments.

When testing your load, pay close attention to the pressure and velocity readings. Aim for a pressure of 55,000-60,000 psi and a velocity of 3,000-3,100 ft/s. This will give you a safe and effective load for hunting large game like elk.

Practical Considerations for Elk Hunting

When hunting elk with the 7mm SAUM, it’s essential to consider the range and shot placement. Elk can be a long-range animal, and a shot at 500-600 yards is not uncommon. To ensure a clean and quick kill, aim for a spot behind the shoulder, just above the heart.

When loading for elk hunting, prioritize a flat-shooting load with minimal wind deflection. A load with a high ballistic coefficient and a moderate burn rate will provide the best results. With the right load and proper shot placement, the 7mm SAUM is an effective and reliable choice for hunting elk.
